Blackburn and Bolton are the warning signs. Stable midtable clubs without a lot of money who challenged for europe and then appointed the wrong guys, had one bad season too many and ended up in the crap.
But with respect we're not bolton or blackburn and otoh there's wigan who are a tiny club who have just managed to do enough to stay in the league.
Our level financially is about 10th to 15th, our level in footballing terms based on our squad is 4th-7th. It would have to be a really bad manager who'd take this team into a relegation fight and a relatively bad manager to take our club there.
Any manager who's even average in terms of top flight managers should keep us clear of the dog flight as a minimum with what he'll inherit this summer.
If you look at our side/squad then anyone that'd get that squad in the bottom three doesn't deserve to earn any kind of living out of football
